Full Story

The U.S. Fish and Wildlife Service is currently promoting National Invasive Species Awareness Week by encouraging Americans to help control certain troublesome animal populations by eating them.

Observed this year from Feb. 24 to Feb. 28, the awareness campaign aims to educate the public on the impact of invasive species. Scientists say invasive species can outcompete native wildlife, degrade habitats and disrupt ecosystems.

To mitigate these effects, officials have released a list of invasive species that can be consumed as a food source.

Nutria

Originally from South America, nutria have spread across the Gulf Coast, Atlantic Coast and Pacific Northwest after being introduced through the fur trade.

These rodents contribute to wetland degradation by damaging marsh vegetation and soil. The animals sometimes cause permanent resource loss. Their meat is described as lean and mild, with higher protein and lower cholesterol levels compared to chicken or beef.

Northern snakehead

Native to East Asia, the northern snakehead is now found in mid-Atlantic and southeastern waterways. Scientists say this is likely due to unauthorized releases from fish markets.

Known for their ability to survive out of water for extended periods, they are aggressive predators that disrupt local fish populations. The fish is considered firm, flaky and versatile for cooking.

Green iguana

Green iguanas originated from Central and South America but this species has now established populations in Florida and other warm U.S. regions. The animals consume native plants, compete for habitats and contribute to structural damage.

People commonly use the animal’s meat in stews, tacos and other dishes, with a taste often compared to chicken.

Carp (bighead, silver, black carp and grass carp)

Introduced from East Asia in the 1970s to control algal blooms, carp have since spread through Midwest and Southeast rivers and lakes. Scientists say they compete with native fish and their resources.

While utilized in various culinary preparations, such as grilling and frying, proper cleaning is necessary due to their bottom-feeding nature.

Feral hogs

Brought to the U.S. from Europe and Asia, feral hogs are prevalent in Texas, California and the southeastern states. They cause significant agricultural and environmental damage. The U.S. Department of Agriculture estimates the hogs create about $1.5 billion worth of damage annually.

Many states encourage hunting as a management strategy. Some companies offer hunting-related recreational experiences. Feral hog meat is used in barbecue, chili and other dishes, with a flavor similar to domesticated pork but slightly gamier.

What happens next?

While consuming invasive species may help control their populations, experts stress that it should be part of a larger conservation strategy. Wildlife management efforts, including regulated hunting and fishing, continue to play a role in addressing invasive species and mitigating their environmental impact.
